Abstract: Une cellule solaire à l'arséniure de gallium (6) possède une couche fenêtre à l'arséniure de gallium aluminium (20) dans laquelle des lignes de contact métalliques fines (40) s'étendent au travers de la fenêtre à l'arséniure de gallium aluminium (20) pour faire contact électrique avec la couche émettrice (14), et une pluralité de lignes d'une grille métallique (50) disposées sur la couche fenêtre (23) traversent les lignes de contact, faisant ainsi contact électrique avec les lignes de contact métalliques (40). Une bande métallique plate (60) s'étendant le long d'un des bords de la cellule solaire effectue la connexion électrique des lignes de la grille (50) entre elles. En conséquence, deux métaux séparés peuvent être utilisés, l'un ayant de bonnes propriétés de contact ohmique pour les lignes de contact métalliques (40) et l'autre ayant de bonnes propriétés de conduction de courant et d'adhésion pour les lignes de la grille métallique (50). De plus, les lignes de contact métallique (46) peuvent être conçues très étroites pour réduire la zone de contact sur la couche émettrice (14) réduisant ainsi le courant de recombinaison dans la couche émettrice.

Date May 18, 1989.The invention relates to a process for the preparation of aqueous dispersions to be further processed to electrocoating paints with baking temperatures below 160 DEG  C. and baking times</=30 minutes, which dispersions contain modified epoxide-amine adducts as binders and polyisocyanates blocked by hydroxyl groups as cross-linking agents. In this process polyepoxides and compounds containing one or more, preferably 2, hydroxyl groups per molecule are reacted at elevated temperatures in the presence of catalysts to furnish epoxide-containing intermediates. A solvent or a mixture of solvents is then added with external cooling ahd the solution is boiled under reflux, if necessary in vacuo, until the temperature of the solution drops to 95 DEG  C. to 20 DEG  C. Amines are then added onto the epoxide groups which are still present in a free state in the epoxy resin and a dispersion is prepared by adding a water/acid mixture after adding the crosslinking agent or the dispersion is first prepared and the crosslinking agent is added subsequently.
